We have the List with three values, 5, John and C#. And we want to access the second element i.e. John.
using System.Collections.Generic;
public class MyApplication
{
public static void Main(string[] args)
{
var x = new List<object>(){5, "John", "C#"};
System.Console.WriteLine(x[1]);
}
}
So, in the above code we have created a List and initialised to the variable x.
var x = new List<object>(){5, "John", "C#"};Now, let us see, how the values are positioned in the List

So, as we can see the elements are positioned as 0, 1 and 2. And if we want to access the second element, we can refer to the position 1 using the square brackets (i.e. x[1]).
And the print statement prints the value of the second element of the List (i.e. John).
System.Console.WriteLine(x[1]);
